Alphabet Rangoli Python
Problem Statement :
You are given an integer, N. Your task is to print an alphabet rangoli of size N. (Rangoli is a form of Indian folk art based on creation of patterns.) Different sizes of alphabet rangoli are shown below: #size 3 ----c---- --c-b-c-- c-b-a-b-c --c-b-c-- ----c---- #size 5 --------e-------- ------e-d-e------ ----e-d-c-d-e---- --e-d-c-b-c-d-e-- e-d-c-b-a-b-c-d-e --e-d-c-b-c-d-e-- ----e-d-c-d-e---- ------e-d-e------ --------e-------- #size 10 ------------------j------------------ ----------------j-i-j---------------- --------------j-i-h-i-j-------------- ------------j-i-h-g-h-i-j------------ ----------j-i-h-g-f-g-h-i-j---------- --------j-i-h-g-f-e-f-g-h-i-j-------- ------j-i-h-g-f-e-d-e-f-g-h-i-j------ ----j-i-h-g-f-e-d-c-d-e-f-g-h-i-j---- --j-i-h-g-f-e-d-c-b-c-d-e-f-g-h-i-j-- j-i-h-g-f-e-d-c-b-a-b-c-d-e-f-g-h-i-j --j-i-h-g-f-e-d-c-b-c-d-e-f-g-h-i-j-- ----j-i-h-g-f-e-d-c-d-e-f-g-h-i-j---- ------j-i-h-g-f-e-d-e-f-g-h-i-j------ --------j-i-h-g-f-e-f-g-h-i-j-------- ----------j-i-h-g-f-g-h-i-j---------- ------------j-i-h-g-h-i-j------------ --------------j-i-h-i-j-------------- ----------------j-i-j---------------- ------------------j------------------ The center of the rangoli has the first alphabet letter a, and the boundary has the Nth alphabet letter (in alphabetical order). Input Format: Only one line of input containing N, the size of the rangoli. Constraints: 0<N<27 Output Format: Print the alphabet rangoli in the format explained above.
Solution :
Solution in C :
n=int(input())
for i in range(n-1,-1,-1):
for j in range(i):
print(end="--")
for j in range(n-1,i,-1):
print(chr(j+97),end="-")
for j in range(i,n):
if j != n-1:
print(chr(j+97),end="-")
else:
print(chr(j+97),end="")
for j in range(2*i):
print(end="-")
print()
for i in range(1,n):
for j in range(i):
print(end="--")
for j in range(n-1,i,-1):
print(chr(j+97),end="-")
for j in range(i,n):
if j != n-1:
print(chr(j+97),end="-")
else:
print(chr(j+97),end="")
for j in range(2*i):
print(end="-")
print()

Enter-View ( EV ) is a linear, street-like country. By linear, we mean all the cities of the country are placed on a single straight line - the x -axis. Thus every city's position can be defined by a single coordinate, xi, the distance from the left borderline of the country. You can treat all cities as single points. Unfortunately, the dictator of telecommunication of EV (Mr. S. Treat Jr.) do
